how to use dll in mql4 to make ea

[milanese]

hello,

i want to make ea like trade copier. i want to use a dll, like windows user32.dll bcoz i found many of them use it.they used two func of this dll

#import "user32.dll"
int PostMessageA(int hWnd,int Msg,int wParam,int lParam);
int RegisterWindowMessageA(string lpString);
#import

my question is,
1) what parameter i send to with this function like int PostMessageA(what,what,what,what).

2) i read somethings like 10milisecond execution , what i that, is this possible using this dll only.

3) i want some example how this dll works with the code, is that use only in the import section or it has any other uses.

plaese give some coding example or any tradecopier in mql4 version.
